WELDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 642,482, dat-ed January 30, 1900.

Application filed March 22, 1899. Serial No. 710,086. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, ANDREW K. PE'rERsEN, a citizen of the United States, residing at Sleepy Eye, in the county of Brown and State of Minnesota, have invented certain new and useful Improvements in Pressure Welding- Machines, of which the following is a specification.

My invention relates to improvements in welding-machines by means of which 'the welding is performed by pressure.

A particular description of the machine is hereinafter fully described, and pointed out in the claim.

In the accompanying drawings, Figure lis a side view of the machine. Fig. 2 is a longitudinal vertical section thereof. Fig. 3 is a top plan view. Figs. Ltand 5 are cross-sections on the line a b of Fig. 1.

'Ihe numeral 1 represents a table secured to the standards or legs 2.

3 represents suitable brackets provided with the bearings, and 4 an anvil-supporter, these parts constituting the frame of the inachine. An eccentric 5 is secured to a shaft 6, which is journaled in the bearings 3 and is provided with the lever 7. The table 1 is provided with a slot8, in which is loosely mounted a block 9, which is loosely held to the table by means of the cross-pin 10. Block 9 is further provided with a slot 11 and adapted to receive the tongue ofthe welding-iron 12, which is secured thereto by means of the bolt 13.

The block 9 is connected with the eccentric.

5 by means of the straps 16, which straps are provided with elongated slots 17, through which extend screws 17, which are screwed into the sides of the block 9, so as to enable the block 9 and welding-iron 12 to be moved in contact with the anvil 15 by means of the eccentric 5 and withdrawn by means of the straps 16.

The anvil-supporter 4 is provided with a slot 14, adapted to receive the anvil 15. The press is secured toaiioor by means of the rod 19, hook 20, and nut 21.

I would have it understood that the anvil 15 and the welding-iron 12 are removable, so that they may be respectively replaced with blocks suitable for the different kinds of work desired to be welded together. If, for instance, I should desire to weld a toe-calk to a horseshoe, I then employ an anvil provided with a recess 1S, in which the toe-calk its, as

shown in Fig. 2. Furthermore, by adjustably attaching the welding-iron to the eccentric in the manner described the machine may be quickly adapted for welding articles of dit' Vferent thickness, and the degree of pressure straps 16, when the ends of the slots are reached, operate to retract the block 9 and iron 12. As shown, the points of attachment between the straps and the eccentric are farther removed from the pivotal point of the eccentric than is the part of the eccentric which bears against the block 9, and hence by slotting the straps and securing them to the block in the manner shown when the eccentric is turned to move forward the block the straps will move faster and in advance of the screws 17 whereby nostrain can possibly be placed on the straps during the pressing or welding operation.

What I claim is- In a welding-machine, the combination with a longitudinally-slotted table provided at one end with a removable anvil and at the opposite end with two fixed brackets, of a journalpin journaled in said brackets, an eccentricfixed near its upper edge on said j ournal-pin, a block movable longitudinally on said table between the eccentric and anvil and having a depending portion extending through the slot in the table, a pin passed transversely through said depending portion beneath the table, screws fitted in the sides of the block, slotted straps iitted over said screws at one end and at their opposite ends attached to the eccentric at points opposite the pivotal point of the latter, and a lever for turning the eccentric, substantially as described and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
